FFmpegDotNet

Another FFmpeg compliance which reads media properties and then forward to FFmpeg to processing like encoding, extracting and more. This mainly use for Internet Friendly Media Encoder

What is difference with MediaInfo?

MediaInfo is great tool to display media properties, much more details than FFmpeg it self, however I find so difficult to play with MediaInfo & FFmpeg, for example capture media properties with MediaInfo.dll and use that info to FFmpeg.exe, mostly it work just fine, until FFmpeg rejects because MediaInfo provides different what FFmpeg needs

For example media index/id, some are start from 1, some are start from 0. MediaInfo follow actual indexing/id but FFmpeg always start from 0. When you try mapping, FFmpeg will reject.

Usage

Using FFmpegDotNet very stright forward

Capture media properties

FFmpeg.FFmpegProbe = Path.Combine("ffmpeg", "64", "ffprobe"); // set binary file

var info = new FFmpeg.GetInfo(@"D:\Users\Anime4000\Videos\ASDF COMP- BALLZ.mp4");

string fmtName = info.FormatName;
string fmtName2 = info.FormatNameFull;
float time = info.Duration;
ulong size = info.FileSize; // in bytes
ulong bitRate = info.BitRate; // in bits

Console.WriteLine($"Format: {fmtName} ({fmtName2}),\nSize: {size}bytes,\nBitrate: {bitRate}bps,\nLength: {time}sec\n");

foreach (var item in info.Video)
{
	Console.Write($"ID               : {item.Id}\n");
	Console.Write("Type             : Video\n");
	Console.Write($"Language         : {item.Language}\n");
	Console.Write($"Codec            : {item.Codec}\n");
	Console.Write($"Pixel Format     : {item.Chroma}\n");
	Console.Write($"Bit per Colour   : {item.BitDepth}\n");
	Console.Write($"Resolution       : {item.Width}x{item.Height}\n");
	Console.Write($"Frame Rate       : {item.FrameRate:#.##}fps\n");
	Console.Write($"Frame Rate Avg   : {item.FrameRateAvg:#.##}fps\n");
	Console.Write($"Frame Rate Mode  : {(item.FrameRateConstant ? "Constant" : "Variable")}\n");
	Console.Write($"Frame Count      : {item.FrameCount} frame's\n");
	Console.Write($"\n");
}

foreach (var item in info.Audio)
{
	Console.Write($"ID               : {item.Id}\n");
	Console.Write("Type             : Audio\n");
	Console.Write($"Language         : {item.Language}\n");
	Console.Write($"Codec            : {item.Codec}\n");
	Console.Write($"Sample Rate      : {item.SampleRate}Hz\n");
	Console.Write($"Bit Depth        : {item.BitDepth} Bit (raw)\n");
	Console.Write($"Channels         : {item.Channel}\n");
	Console.Write($"\n");
}

foreach (var item in info.Subtitle)
{
	Console.Write($"ID              : {item.Id}\n");
	Console.Write("Type            : Subtitle\n");
	Console.Write($"Language        : {item.Language}\n");
	Console.Write($"Codec           : {item.Codec}\n");
	Console.Write($"\n");
}

foreach (var item in info.Attachment)
{
	Console.Write($"Attachment: {item.Id}, {item.FileName}, {item.MimeType}\n");
}

Console.Read();

With that code, it will display like this (console)

Processing

// Extract Attachment like fonts
new FFmpeg.Process().ExtractAttachment("/home/anime4000/kawaii.mp4", "/home/anime4000/fonts/");

// to do: doing encoding & decoding in the future

Contribute

This code written in C# 7.2, so you need Visual Studio 2017

Clone

You need clone these in same root directory, so FFmpegDotNet can link

git clone https://github.com/Anime4000/FFmpegDotNet
git clone https://github.com/JamesNK/Newtonsoft.Json
MSBuild

Then you can open Visual Studio Project file

To use in your project, is better to use "Add existing project" and dont forget to include Newtonsoft.Json as well
